Gibbs Free Energy and Equilibrium

[Annalyn Diaz 1J]

Why is Gibbs free energy 0 at equilibrium?

[Philipp_V_Dis1K]

The reaction is "at completion" so there is nothing spontaneous to drive the reaction forward or backward

[Cynthia Aragon 1B]

Gibbs free energy is a measure of how much potential a reaction has left to do a "net" something . If the free energy is 0 that means the reaction has reached equilibrium and no work can be done.

[Lorena Zhang 4E]

When the gibbs free energy is zero, the reaction is at equilibrium because neither the forward nor the reverse reaction is favored.

[katie_sutton1B]

At zero, there is no more work that can be done, and the reaction does not favor either the reactants or products. Thus, it is at equilibrium.

[Dong Hyun Lee 4E]

There is no more "free energy" to do work because the reaction is at equilibrium and so a foward nor a backwards process is favored. Think about a ball in a valley, if the ball is on an incline, it will roll down. However if the ball is at equilibirum or the lowest point of the valley, the ball will not move anywhere.
